I have gstreamer installed on a mac and am getting the following conflicts when I run a simple test. How can I resolve these?

gst-launch-1.0 --version

gst-launch-1.0 version 1.24.3

GStreamer 1.24.3

I’ve tried to remove both of them - one at a time - and brew refuses as they are both required. Note I haven’t tried to force removal:

% brew remove gtk+3

Error: Refusing to uninstall /opt/homebrew/Cellar/gtk+3/3.24.42

because it is required by gstreamer, which is currently installed.

You can override this and force removal with:

brew uninstall --ignore-dependencies gtk+3

% brew remove gtk4

Error: Refusing to uninstall /opt/homebrew/Cellar/gtk4/4.14.4

because it is required by gstreamer, which is currently installed.

You can override this and force removal with:

brew uninstall --ignore-dependencies gtk4

Can someone please help? Thank you.

Appears I may have “solved” this, partially. I removed the Homebrew version of gstreamer and instead am running only the Apple Library/Framework, IOW, both the universal & devel .pkgs for 1.24.3 which is the most current version.

gst-launch-1.0 --version

returns the following:

gst-launch-1.0 version 1.24.3
GStreamer 1.24.3
Unknown package origin

Am now getting the following error when compiling the very simple tutorial5, which uses gtk.:

Package ‘gtk4’ requires ‘gio-2.0 >= 2.76.0’ but version of gio-2.0 is 2.74.4

Do the macOS .pkg files use a different version of gtk (which uses glib which houses gio) than the Homebrew distribution?

Will post separately as well.
